## Abstract

There is provided an electric braking device for a vehicle, which includes a brake caliper which is provided to a wheel, a pressing member which is provided to the brake caliper and is driven to press a friction member to a rotary member fixed to the wheel, an electric motor which is a power source to drive the pressing member, an electric power/signal line which supplies electric power to the electric motor or allows a first electric circuit provided in a vehicle body to communicate with a second electric circuit provided in the brake caliper, and a connector which relays the electric power line. The connector includes a terminal joining portion which joins one terminal and another terminal to each other, and the one terminal and the another terminal are made of metal. The terminal joining portion is positioned inside the brake caliper.

## Claims

### Claim 1

An electric braking device for a vehicle, which is configured to generate braking torque on a wheel of the vehicle, the electric braking device comprising:
a brake caliper which is provided to the wheel;
a pressing member which is provided to the brake caliper and is configured to be driven to press a friction member to a rotary member which is fixed to the wheel and rotates together with the wheel;
an electric motor which is a power source to drive the pressing member;
an electric power line which is configured to supply electric power to the electric motor from an electric power source which is fixed to a vehicle body of the vehicle; and
a connector which is configured to relay the electric power line,
wherein the connector includes a terminal joining portion which joins one terminal and another terminal to each other, the one terminal and the another terminal being made of metal, and
wherein the terminal joining portion is positioned inside the brake caliper.

### Claim 2 (depends on 1)

The electric braking device according to claim 1,
wherein the brake caliper includes a case member which has a space to accommodate the terminal joining portion, and
wherein the terminal joining portion is configured by joining the another terminal which is introduced to the space of the case member through an opening portion provided to penetrate the case member, to the one terminal which is arranged in the space of the case member.

### Claim 3

An electric braking device for a vehicle, which is configured to generate braking torque on a wheel of the vehicle, the electric braking device comprising:
a brake caliper which is provided to the wheel;
a pressing member which is provided to the brake caliper and is configured to be driven to press a friction member to a rotary member which is fixed to the wheel and rotates together with the wheel;
an electric motor which is a power source to drive the pressing member;
a signal line which allows a first electric circuit provided in a vehicle body of the vehicle to communicate with a second electric circuit provided in the brake caliper; and
a connector which is configured to relay the signal line,
wherein the connector includes a terminal joining portion which joins one terminal and another terminal to each other, the one terminal and the another terminal being made of metal, and
wherein the terminal joining portion is positioned inside the brake caliper.

### Claim 4 (depends on 3)

The electric braking device according to claim 3,
wherein the brake caliper includes a case member which has a space to accommodate the terminal joining portion, and
wherein the terminal joining portion is configured by joining the another terminal which is introduced to the space of the case member through an opening portion provided to penetrate the case member, to the one terminal which is arranged in the space of the case member.
